I've just finished reading Ed Gorman's Cavalry Man: Powder Keg, a western that takes place in 1883-4. (Unsolicited plug: It's a darned fine book, as are all of Gorman's -- give it a try.) One thing that bothered me just a tad, though: twice in the book Gorman made reference to several townspeople being members of Rotary. The Rotary that I'm familiar with (the Chicago club that grew into Rotary International) was begun in 1905.
Was there a previous organization named Rotary, or was this just an error on Gorman's part? Inquiring people want to know?
